I have already assigned the key to isbn but it says my foreach statement needs to assign the key to a temporary variable named $isbn.
<?php
$books["978-0743261690"] = "Gilgamesh";
$books["978-0060931957"] = "The Odyssey";
$books["978-0192840509"] = "Aesop's Fables";
$books["978-0520227040"] = "Mahabharta";
$books["978-0393320978"] = "Beowulf";

<?php foreach($books as $key => $book) { ?>
<li><?php echo $book;
$isbn = $key;
?></li>
<?php } ?>
</ul>
